#===========================================================================
# Makefile for UnZip, ZipInfo, fUnZip, MakeSFX      AMIGA SAS/C Version 6.58
# Version:  5.53                                    last revised:  25 Dec 06
#===========================================================================
# from John Bush <john.bush@east.sun.com>
#            or: <JBush@bix.com>

# updated for SAS/C Version 6.56+ and AmigaDOS 3.1 (V40)
# by Haidinger Walter <walthaid@unix.ict.tuwien.ac.at>

# additional supplements and maintenance by Paul Kienitz

# This makefile should work with at least AmigaDOS 2.04 (V37)  (not tested)
# and will probably not work with AmigaDOS 1.3 (V34)

# If you have any improvements, critics or else please feel free to mail.
# Any response is appreciated. Haidinger Walter <walthaid@unix.ict.tuwien.ac.at>

# Available targets:
# all           builds all executables below
# unzip         builds unzip executable
# unzipsfx      builds unzipsfx executable
# funzip        builds funzip executable
# makesfx       builds makesfx executable
# clean         remove all files created by the compilation
# spotless      like clean target but removes binaries too


##########################
# USER MACRO DEFINITIONS #
##########################

# Set the processor to generate code for UnZip and fUnZip. Specify one of:
# ANY 68000 68010 68020 68030 68040 68060  (Default: ANY or 68000)

# Use of the assembly versions is not supported yet since some of the asm
# source file do not assemble with 68000 instructions.
# Any help is appreciated of course.

CUSECPU = ANY

# Uncomment both CUTIL and LUTIL to make use of utility.library of OS 2.04+
# The utility.library is *not* used for UnZipSFX to ensure maximum portability
# between the different Amiga systems (minimal config: 68000 and OS 1.2).
# You can change this by adding the $(LUTIL) macro in the UnZipSFX linking
# rules (See below: Final output targets, UnZipSFX:).
# WARNINGS when using the utility library:
# 1. All Executables will *only* work with AmigaDOS 2.04 (v37) or higher.
# 2. You *need not* compile/link with short-integers using the
#    utility.library. It will crash your machine. See Libraries below.
#
# Default: commented (not used)
#
#CUTIL = UTILLIB DEFINE=_UTILLIB
#LUTIL = WITH SC:LIB/utillib.with    # include necessary linker defines


# Choose one stack-handling method (default=faster)
# StackExtend: Dynamic runtime stack extension. You won't notice stack overflows.
# StackCheck: On a stack overflow a requester appears which allows you to exit.
# Note that either stack watching will slow down your executable because of the
# extra code run on each function entry. On the other hand, you won't crash
# anymore due to stack overflows. However, you should not have *any* stack
# problems with info-zip if you raise your stack to 20000 (which I'd
# recommend as a minimum default stack for all applications) or more using the
# shell stack command. Type 'Stack 20000' or add it to your S:Shell-Startup.
# BTW: Typing 'Stack' prints your current stack size.
#
CSTACK = NOSTACKCHECK STACKEXTEND     # slow, but always works
#CSTACK = STACKCHECK NOSTACKEXTEND    # slow, requester & graceful exit
#CSTACK = NOSTACKCHECK NOSTACKEXTEND  # faster but relies on larger stack (>=10K)

#
# LIBRARIES
# ---------

# Choose one DATAOPTS , SASLIB and LSTARTUP
# Always comment/uncomment all macros of a set.

# Library to use with near data and 2-byte integers
# Notes: o  slower than 4-byte integers with 68000 cpu
#        o  *not* recommended due to poor overall performance
#        o  see comment in amiga/osdep.h
#DATAOPTS = DATA=NEAR SHORTINTEGERS DEF=_NEAR_DATA
#SASLIB   = scs
#LSTARTUP = cres.o

# Library to use with near data and 4-byte integers (DEFAULT)
# *** use this with the utility.library ***
DATAOPTS = DATA=NEAR DEF=_NEAR_DATA
SASLIB   = sc
LSTARTUP = cres.o

# Library to use with far data and 2-byte integers
# use if DYN_ALLOC is not defined
# old default - far data always works but is slower
#DATAOPTS = DATA=FAR SHORTINTEGERS DEF=_FAR_DATA
#SASLIB   = scsnb
#LSTARTUP = c.o

# Library to use with far data and 4-byte integers
# if everything else fails: try this
#DATAOPTS = DATA=FAR DEF=_FAR_DATA
#SASLIB   = scnb
#LSTARTUP = c.o


#
# DEBUGGING
# ---------

# Default: No debugging information added.
# The two macros below will be overwritten if you choose to add
# debug info, therefore need to comment.
CDBG = NODEBUG NOPROFILE NOCOVERAGE    # default: no debug info
LDBG = STRIPDEBUG                      # default: no debug info

# Compiler and loader debug flags.  Uncomment as needed.  Recomment when done.
# Optimization disabled for faster compilation (by using NOOPT)
#CDBG1 = DEF=DEBUG DEF=DEBUG_TIME     # enables Info-ZIP's debug output

# Enable profiling and coverage when desired. Option COVERAGE commented
# seperately because running coverage may corrupt your drive in case of a
# system crash since a file 'cover.dat' is created in your working directory.
# Note that the use of COVERAGE forces the use of the c.o startup module.
#CDBG2 = PROFILE
#CDBG3 = COVERAGE        # must use c.o startup code:
#LSTARTUP = c.o          # Uncomment *only* when you use COVERAGE

# *Uncomment* _HERE_ macros CDBG and LDBG to include debugging information
#CDBG = $(CDBG1) $(CDBG2) $(CDBG3) ADDSYM DEBUG=FULLFLUSH STACKCHECK NOOPT
#LDBG = ADDSYM
# Optional use of memwatch.library which can be found in your
# sc:extras/memlib directory. Please read the short docs (memlib.doc).
# Note that memlib has a small bug: MWTerm() displays always the first entry.
# Get the latest version from aminet (dev/debug/memlib.lha) or
# contact me to get the patch. Uncomment all macros to use.
#CMEMLIB  = DEFINE=MWDEBUG=1       # define to enable library
#LMEMLIB  = SC:LIB/memwatch.lib    # path to library
#LSTARTUP = c.o                    # must use c.o with memlib!

#
# Read environment variable LOCAL_UNZIP and convert options from old Lattice
# v5 to new SAS/C v6 format. You may also use the new DEFINE= syntax but
# be sure not to mix v5 and v6 options, otherwise lctosc will be confused.
#
# e.g.: to define FOO_ONE and FOO_TWO enter:
#
# SetEnv LOCAL_UNZIP "-DFOO_ONE -DFOO_TWO"
#
# To make this permanent, i.e. survive an reboot, put the statement into
# your startup-sequence or (for AmigaDOS 2.0 or higher only) make sure
# LOCAL_UNZIP is stored in the ENVARC: directory too. To do this, simply
# copy the file from ENV: to ENVARC:
#   Copy ENV:LOCAL_UNZIP ENVARC:
#
# For a list of all valid non-standard compilation options see the INSTALL
# file in the root zip tree. Please read the notes there before using the
# non-standard options.
#
# e.g.: To use the non-standard timezone environment variable "INFOZIP_TZ"
#	(or another arbitary name) instead of "TZ", type in your shell:
#
#	Setenv LOCAL_UNZIP "-DTZ_ENVVAR=*"INFOZIP_TZ*""
#
# Note that you need to escape the quotes of INFOZIP_TZ with leading stars.
# To verify that LOCAL_UNZIP has been saved correctly, use the Getenv command:
#
#	Getenv LOCAL_UNZIP
#
# ...should display:
#
